It was the late summer of 1988, and I found myself sitting in a small, dimly lit television studio in Manhattan.

I was there for one of those retrospective interviews that seem to follow you when you have been part of a show that refuses to leave the airwaves.

The air in the studio was thick with that peculiar smell of ozone from the lights and the scent of expensive cologne.

The interviewer was a very polite young man who clearly grew up watching us every Friday night on a flickering screen.

He reached into a manila folder and pulled out a grainy, black-and-white photograph.

It wasn’t a publicity still. It was a candid shot from the set of Stalag 13, taken during a break in filming the third season.

In the photo, I am standing there in that ridiculous, high-collared uniform, the monocle firmly in place, but I am holding a soggy deli sandwich in one hand and looking absolutely exhausted.

I looked at that photo and I could almost smell the dust of the old Desilu backlot.

I told the young man that people often forget we weren’t just playing characters; we were living in those costumes for twelve to fourteen hours a day.

The monocle was the trickiest part, of course.

I had to train my facial muscles so it wouldn’t drop at the wrong time, but after a month of filming, it became a part of my actual anatomy.

I could sneeze, bark orders at John Banner, or even run across a muddy field, and that little piece of glass stayed perfectly still.

The interviewer laughed and asked if the character ever bled into my real life.

I leaned back, the memory of a specific trip to Chicago bubbling up to the surface.

It was right at the height of the show’s popularity, and I was traveling alone, trying to maintain some semblance of a normal life.

I was at O’Hare airport, waiting for a delayed flight to Los Angeles, and I noticed a man in a very sharp, grey suit watching me from across the boarding gate.

He didn’t look like a typical fan or an autograph seeker.

He looked worried, his brow furrowed in deep concentration.

He stood up, adjusted his tie, and began walking toward me with a look of absolute, terrifying determination.

I thought he was going to complain about the show or perhaps my performance.

He leaned in and looked me straight in the eye.

The man stopped exactly two feet in front of me, his face a mask of total gravity.

He didn’t smile, and he didn’t ask for a signature.

Instead, he leaned in very close, so close I could smell the peppermint on his breath, and he whispered, “Colonel, I just wanted to let you know… the tunnel is behind the stove in the kitchen.”

I sat there, frozen in my plastic airport chair.

I didn’t know whether to laugh, run for the exits, or call for airport security.

He gave me a wink—a slow, conspiratorial wink that suggested we were both deep undercover—and then he just turned around and walked away, disappearing into the crowd.

That was the moment I truly realized the beautiful, absurd monster we had created with Hogan’s Heroes.

When I got back to the set in Los Angeles and shared this story with the cast, the reaction was pure, unadulterated chaos.

John Banner, our dear, wonderful Schultz, laughed so hard he actually knocked over a tray of coffee in the commissary.

He kept shouting, “Werner! They are helping you! Finally, someone is on your side!”

Bob Crane was leaning against a prop truck, shaking his head and laughing, saying that if the fans were starting to feed the Commandant intel, his job as Hogan was going to get a lot harder.

But it wasn’t just a funny coincidence; it became a legendary story on the set because it highlighted the bizarre, surreal world we inhabited.

We were making a comedy about a prisoner-of-war camp, which was always a risky proposition.

I had always insisted, as a condition of my contract, that Colonel Klink must never, ever succeed.

He had to be the fool. He had to be the one who was constantly outwitted by the prisoners.

And yet, here was a man in the real world who felt such a strange, misplaced sympathy for this bumbling officer that he felt the need to warn him about the tunnels.

The crew never let me hear the end of it for the rest of the season.

Every time I would walk onto the set, one of the grips or the camera operators would hiss from the rafters, “The tunnel is behind the stove, Colonel!”

Even the director got in on the joke.

We would be in the middle of a high-tension scene where Hogan was spinning some elaborate lie to cover up a sabotage mission, and the director would yell, “Cut! Werner, remember, a man in Chicago told you where the tunnel is. Use that motivation for your next line!”

It became this internal shorthand for the absurdity of our fame.

I think that’s why the show worked so well for so long.

There was a genuine warmth between us—Bob, John, Richard Dawson, Robert Clary, and the rest—that allowed us to find the humor in even the most ridiculous situations.

We knew what we were doing was a high-wire act of tone and taste.

If we played it too straight, the show became grim and depressing.

If we played it too broad, it became a hollow cartoon.

But when the public starts treating you like the actual person you are parodying, you know you’ve struck a very strange, deep chord in the cultural psyche.

I remember talking to Robert Clary about it later that year.

Robert, who had actually survived the concentration camps in real life, had the most profound take on the Chicago airport incident.

He told me, “Werner, if they are telling you where the tunnels are, it’s because they aren’t afraid of you. And that is the greatest victory we have.”

That stayed with me for the rest of my career.

The humor on that set was our shield and our connection to the audience.

We laughed because the alternative was unthinkable, given the historical weight of the setting.

And so, every time a fan would come up to me with that specific glint in their eye, I stopped trying to explain that I was a classically trained actor.

I would just fix my monocle, look them in the eye with my best Klink scowl, and say, “I see nothing! I hear nothing!”

The roar of laughter that would follow was worth more than any prestigious award or glowing review.

It was a reminder that we were providing a bit of light and a lot of laughs in a world that can often be very dark.

Even now, when I see a rerun late at night, I don’t see the mistakes or the low-budget effects.

I see a group of friends who were incredibly lucky to find each other on a soundstage in California.

I see a man in a Chicago airport who just wanted to help a bumbling Colonel catch a clever prisoner.

It makes me smile every single time I think about it.

We took the work seriously, but we never took ourselves seriously, and I think that’s why the tunnels stayed open for so many years.

Humor is often the only way to make sense of a world that insists on being nonsensical.

Do you have a favorite memory from a show that shouldn’t have worked, but did?
